Senior Solutions Architect, Payments

About the role

CommBank's Business Banking Technology team is looking for a Senior Solutions Architect, Payments, based in the Sydney CBD area. You will shape secure, resilient and scalable solutions across domestic, international and high-value payments, leading end-to-end solution architecture for account-to-account payments and influencing Payments strategy, modernisation and architecture across multiple technology crews.

Key responsibilities

• Lead end-to-end solution architecture for complex payment initiatives across multiple delivery crews, setting architectural direction and helping teams make pragmatic trade-offs.
• Shape the Payments domain architecture and translate strategic direction into practical solution designs.
• Establish and promote reusable architecture patterns, guardrails and API standards, and guide engineering teams to apply them consistently.
• Design secure, scalable and highly available solutions that meet resilience, risk and regulatory expectations.
• Own significant architecture decisions from concept through delivery, and engage with engineers and technical leads to turn designs into implementable patterns.
• Design for operability, observability and recoverability, and identify opportunities for generative and agentic AI.
• Produce clear architecture artefacts and drive decisions through architecture and governance forums, partnering with enterprise architecture, engineering, security, risk, product and business teams.

Required profile

• Current Senior Solutions Architect, or an experienced Solution Architect, Technology Architect or Senior Engineering Lead ready to work across a broader architecture landscape.
• Strong architecture capability, technical judgement and relevant domain experience; current title matters less than capability.
• Payments expertise, including Australian domestic payments, international payments, correspondent banking, RTGS and high-value payment ecosystems.
• Strong understanding of ISO 20022 and end-to-end payment lifecycles.
• Experience modernising complex or legacy platforms through domain decoupling, decomposition and progressive modernisation.
• Ability to influence through trust and technical credibility, communicate architecture to technical and non-technical stakeholders, and balance business outcomes, risk and delivery constraints.

Required skills

• Architecture across APIs, microservices and event-driven systems.
• Cloud-native solutions, with AWS experience highly regarded.
• Integration patterns, security, resilience and non-functional design.
• Working knowledge of established architecture methods and practices.
• Understanding of generative and agentic AI and its practical value.
